Two identical sinusoidal waves, each of amplitude A, and differing by their phase constant, interfere to produce a resultant wave with amplitude A_res. As a result of this interference, the amplitude is decreased by 20%. Determine the phase constant p. O p = 2.32 rad O p = 132 rad O p = 3.48 rad O p = 1.87 rad

Two identical sinusoidal waves, each of
amplitude A, and differing by their
phase constant, interfere to produce a
resultant wave with amplitude A_res.
As a result of this interference, the
amplitude is decreased by 20%.
Determine the phase constant p.
O p = 2.32 rad
O p = 132 rad
O p = 3.48 rad
O y = 1.87 rad
To get a full destructive interference
between two waves travelling in the
same direction, a time delay of At = 3
